Cloudera Manager Events

This section provides information on events supported by Cloudera Manager.

An event is a record that something of interest has occurred – a service's health has changed state, a log message (of the appropriate severity) has been logged,
and so on. Many events are enabled and configured by default.

Cloudera Manager supports the following categories of events:

Category

Description

ACTIVITY_EVENT

Generated by the Activity Monitor; specifically, for jobs that fail, or that run slowly (as determined by comparison with duration
limits). In order to monitor your workload for slow-running jobs, you must specify Activity Duration
Rules.

AUDIT_EVENT

Generated by actions performed

In Cloudera Manager, such as creating, configuring, starting, stopping, and deleting services or roles

By services that are being audited by Cloudera Navigator.

HBASE

Generated by HBase with the exception of log messages, which have the LOG_MESSAGE category.

Thresholds for various health tests can be set under the Configuration tabs for HBase, HDFS, Impala, and MapReduce service instances, at both the service
and role level. See Configuring Health Monitoring for more information.

LOG_MESSAGE

Generated for certain types of log messages from HDFS, MapReduce, and HBase services and roles. Log events are created when a log
entry matches a set of rules for identifying messages of interest. The default set of rules is based on Cloudera experience
supporting Hadoop clusters. You can configure additional log event rules if necessary.
